Spreadsheet formulas built for finance.
Formula Genius helps finance teams generate spreadsheet formulas, SQL queries, and regex patterns from plain-English descriptions, then review the output and check supported formulas. Review generated results before using them in your work.
Generate formulas for budgets, forecasts, and financial models. Check supported formulas with sample cases and review the assumptions before use.
"Calculate monthly variance between actual and budget, show as percentage"
=IF(Budget<>0, (Actual-Budget)/Budget, 0)Spreadsheet challenges that finance teams face every day.
Formula errors cost real money
One wrong SUMIFS reference in a quarterly report can misstate revenue by millions. Manual formula auditing takes hours and still misses edge cases.
Financial models are fragile
Nested IFs, complex lookups, and cross-sheet references break silently. You only find out when the board deck has wrong numbers.
Excel version mismatches
Your XLOOKUP works fine on Excel 365 but breaks when the CFO opens it in Excel 2019. Version compatibility is a constant headache.
Real formulas for finance teams
Describe what you need. Review a formula draft and the checks available.
"Calculate NPV of cash flows with a 10% discount rate"
=NPV(0.10, B2:B6) + B1"Sum all revenue entries for Q1 where department is Marketing"
=SUMIFS(amount, date, ">="&DATE(2026,1,1), date, "<"&DATE(2026,4,1), dept, "Marketing")"Monthly revenue trend with month-over-month change"
SELECT month, revenue,
revenue - LAG(revenue) OVER (ORDER BY month) AS mom_change,
ROUND((revenue - LAG(revenue) OVER (ORDER BY month)) / LAG(revenue) OVER (ORDER BY month) * 100, 1) AS mom_pct
FROM monthly_revenue;"Calculate weighted average cost of capital"
=LET(
e_weight, equity/(equity+debt),
d_weight, debt/(equity+debt),
e_weight*cost_of_equity + d_weight*cost_of_debt*(1-tax_rate)
)Features that matter for finance teams.
Edge-case validation
Supported formula checks can compare sample results and flag cases such as division by zero or blank inputs. Review the result’s stated coverage.
Your Excel version
Set your Excel version and generation takes it into account. Need Excel 2016? Say so, then test the result in your workbook.
Financial function library
NPV, IRR, XNPV, XIRR, PMT, FV, PV — all financial functions with proper parameter ordering and common pitfall warnings.
Plain-English explanations
Every generated formula includes a plain-English explanation and step-by-step breakdown. Useful for documentation.
Frequently asked questions
Does Formula Genius handle complex financial models?
Yes. It generates multi-step formulas using LET for readability, handles circular references warnings, and provides alternative approaches for complex calculations like Monte Carlo simulations.
Can it generate SQL for financial reporting?
Absolutely. Revenue recognition queries, cohort analysis, variance reporting — specify your database (PostgreSQL, MySQL, SQL Server) and get optimized queries.
Is the output accurate enough for production financial reports?
Treat generated outputs as drafts. Check supported formulas against expected sample results, review assumptions and coverage, and verify the formula in your workbook before using it in a financial report.
